Rubbing Position Identification Device And Rubbing Position

Rubbing Position Identification Device And Rubbing Position Identification Method For Rotating Machine

Abstract: According to the present invention, a rotating machine has a rotating part that is rotatably supported by a bearing disposed between a first stationary part and a second stationary part. In the case where rubbing has occurred in the rotating machine, a rubbing-position identification device determines whether the position where the rubbing has occurred is a first unit that includes the first stationary part or a second unit that includes the second stationary part, on the basis of AE signals detected at a pair of first AE sensors respectively attached to the first stationary part and the second stationary part.
